This
is a collection of software that imports DXF or STL files and converts
then into gcode. These programs vary in there operation and ease of use
but all generate some form of gcode.

DesKAM 2000
is a Windows 95/98/NT based 2 1/2D Cam program that inputs a DXF file
and creates a Post Processed output file. It can be used for milling,
routing, drilling or anywhere requireing 2 1/2 D toolpath
creation. It performs spiral pockets, contouring, drilling, and
prototyping functions. Besides doing 2 1/2D work Deskam 2000 can import
stereolithography files and lay a toolpath over it. $250 The Demo is limited to 200 line of code

MillWizardCreate
real 3D objects from your favourite 3D modelling program using the new
MillWizard software from Delcam, and almost any 3D milling machine.
Suitable machines range from small CNC desktop hobbyist machines
costing less than $2000 up to 8' by 4' industrial routers. Designed for
users of 3D modelling packages rather than machinists, MillWizard uses
a simple step by step approach which allows anyone to begin creating
real 3D parts from their 3D computer models in minutes.Non Crippled Demo avalible $250

CAD-2-CNC reads drawing-data in DXF- or HPGL-format and generates
CNC-milling-programs. This program is suitable not only for engraving
but also for milling complicated parts in high precision. You draw the
desired tool-paths using a CAD-system e.g. AutoCad. With CAD-2-CNC You
associate parameters like tool-diameter and cutting-speed to the
drawing-elements. The optimized sequence of milling-paths is generated
automatically by CAD-2-CNC. FREE

CAM ExpertThis
is a pretty nice program, I tried the demo and was impressed. Besides
being easy to use it has one of the best toolpath optomization rutiens
I have seen. The program basicly inports dxf, hpgl or gerber files and
outputs gcode. There are to many features to list here so go to there
web site and check it out, Demo avalible $240

Gcode 2000Now
reads lines,Arcs,Rect,Circle,PolyLines,LWPolylines, Ellipse, Sorts
object by size. Reads and writes DXF files.Supports Mechanical desktop,
AutoCAD ,11,12,13,14,2000, Autosketch, TurboCad, DesignCad,
AshlarVellum, CorelDraw and SolidWorks. A note to International users.
Set the decimal delimiter to a period from the Control panel under
Regional settings.Gcode is specifically designed for converting AutoCAD
drawings into G-Code programs for use with any 2-D or 3-D machine such
as Wire EDMs, Laser Etchers, Flame cutting, Milling , Lathes etc. Also
Gcode can be used for creating individual complicated tool paths for
2-D and 3-D machines. Gcode is a low cost opportunity for small
independent machine shops to convert their drawings into useful
programs for their CNC and DNC equipment without the hassle of figuring
out the geometry manually. Version 2000 adds 3d contouring and files up
to 1 million lines. Simply draw the outline of the part on a dedicated
layer. Then DXF out the file. Load the DXF file into Gcode which will
process and plot it. Then simply add Tool numbers Etc. $200

Nester
Nester Requires Windows 95/98/2000 or NT. What Is Nester,
The Product?It is specifically designed for converting CAD
drawings into GCode programs for use with any 2-D or 3-D machine
and then nesting the path into an array across a sheet.Alternativly
existing Gcode tool paths can be processed.Nesting is done on the
XY plane but 3d files can be processed an viewed from any
point. $200

SupercamSuper
Tech & Associates makes computer controlled XYZ tables, Stepper
Motor controllers and the Supcam CAD/CAM program, a direct
machine control Graphics User Interface with a CNC code generator for
CNC machine tool control and CNC code file import features for
stepper motor control via the parallel interface port on a
Desktop computer. HPGL, DXF, BMP and CNC G&M code files can be used
as tool paths.Â Graphic design programs such as CorelDraw
and AutoCAD can be used to generate complex machine tool paths.
